Description

The LMX4168 is a radio transceiver integrated circuit opti-mized for the Digital Enhanced Cordless Telecommunica-tions (DECT) system. The transceiver, when combined witha power amplifier and a Tx/Rx switch, implements a com-plete DECT radio transceiver compliant with the ETSICTR6 standard. The LMX4168 interfaces to National Semi-conductor's SC144XX DECT family of baseband proces-sors.

The LMX4168 integrates a complete transmitter, consistingof a phase locked loop, VCO and PA driver. The receivercontains LNA, quadrature downconverter, polyphase fil-ter/combiner, automatic gain control, and demodulator.

The LMX4168 operates from a single 2.252.75V supply.

The LMX4168 is manufactured in National's 0.25µmCMOS technology, and is packaged in a 44 pin LLP pack-age
